ZIPP 404 Firecrest Carbon Tubeless CL Disc Brake Wheelset 2022


Designed via Zipp’s “Total System Efficiency” (TSE) format, the 404 Firecrest Carbon Tubeless CL Disc Wheelset seamlessly blends aerodynamics, low weight, decreased rolling resistance and comfort to become the perfect choice for road races or efforts against the clock.

The full carbon rims are realised with a hookless tyre interface that helps to reduce weight and increase lateral stiffness. This hookless configuration has a 23mm wide internal measurement to increase the sidewall support of tubeless-ready tyres, allowing them to realise lower rolling resistance and better comfort at lower inflation pressures. The wider inner rim dimension also smooths the tyre-to-rim junction for improved aerodynamics.

The refined, 58mm deep profile of the rims combines with the ABLC surface dimpling to markedly lower drag and afford predictable handling when the wind blows hard from the side. The rims rotate around smooth spinning, well-sealed ZR1 DB hubs, with the rear utilising a 66-point freehub for rapid pedalling engagement. Sapim spokes arranged in a two-cross lacing pattern complete the build, ensuring durability and increased power transfer.


  • 12mm hub end caps
  • Center Lock lock rings


  • The versatile, good-value 404 Firecrest is an exceptional pick for road races or efforts against the clock
  • Conceived via Zipp’s “Total System Efficiency” (TSE) design concept that equally factors aerodynamics, weight, rolling resistance and vibration losses (comfort)
  • A special tool that measures aerodynamic drag, rolling resistance, wind speed and wind yaw angle while on the road, was key in the development of these wheels 
  • The TSE holistic design approach equals more speed in real-world riding conditions rather than just wind tunnels
  • The rims use a high grade of carbon fibre to lower weight, increase strength and improve lateral stiffness
  • The hookless internal rim design is for tubeless-ready tyres only, promotes a more aerodynamic tyre to rim interface and lowers weight via more even resin distribution
  • A 23mm internal rim width works optimally with wider tubeless-ready tyres, lowering rolling resistance and improving comfort
  • Optimised tyre bed for easy tyre installation
  • The 58mm deep, refined rim shape optimises aerodynamic efficiency and crosswind stability
  • An intricate rim surface ABLC dimple pattern further lowers drag
  • ZR1 DB hubs have a better seal design for improved durability and offer a quicker pedalling response thanks to the 66-point engagement free hub
  • 24 spokes front and rear are laced with efficient and durable two-cross lacing patterns
